Antelope Dam, located in Carbon County, Wyoming, is a privately owned structure designed by H.T. Person primarily for water supply purposes. Completed in 1945, this earth dam stands at a height of 18 feet and has a storage capacity of 74 acre-feet. The dam, situated on the Antelope Draw river or stream, serves the city of Alcova and has a surface area of 11 acres.

Despite its low hazard potential, Antelope Dam is rated as being in poor condition as of its last inspection in 2017. The dam's spillway, an uncontrolled type with a width of 400 feet, poses a moderate risk according to assessments. With only one valve as an outlet gate and a drainage area of 4 square miles, the dam is regulated by the Wyoming State Engineer's Office and undergoes regular inspections, enforcement, and permitting.

Overall, Antelope Dam plays a crucial role in providing water supply to the surrounding area. Climate and water resource enthusiasts can appreciate the historical significance and ongoing maintenance efforts of this essential infrastructure in the region.
